U.S. Route 180 is an east–west
United States highway. Like many three-digit routes, US 180 no longer meets its "parent",
US 80. US 80 was decommissioned west of
Mesquite, Texas, and was replaced in
Texas by
Interstate 20 and
Interstate 10 resulting in U.S. 180 being longer than U.S. 80. The highway's eastern terminus is in
Hudson Oaks, Texas (west of
Fort Worth, near
Weatherford), at an intersection with
Interstate 20. Its western terminus is unclear. Signage at an intersection with
State Route 64 in
Valle, Arizona 40 miles (64 km) northwest of
Flagstaff indicates that the route ends at SR 64, which is consistent with the
AASHTO U.S. Highway logs. However, many maps continue the US 180 designation to the south rim of the
Grand Canyon at
Grand Canyon Village. Signage at the SR 64 intersection as late as 2011 indicated that US 180 continues north concurrent with the route. However, no signage along the route exists past this intersection until SR 64 turns east towards
Cameron, Arizona. At this intersection, signage makes no mention of US 180 nor is there any mention at the terminus of SR 64 at
US 89.
